Leaderboarding: Players with 100+ extra-base hits in a season

Only 15 times in history has a player recorded triple-digit extra-base hits in a single season. Here's the list.

Earlier today, as part of our All-Time Single-Season Team series, I noted Albert Belle became the first and still only player in baseball history to rack up 50+ doubles and 50+ home runs in a single season back in 1995. Add one triple to his 52 two-baggers and 50 homers and you get 103 extra-base hits total, tied for the sixth most all-time.

Recording triple-digit extra-base hits in a single-season is a rarity. It has only been done 15 times in history by 12 different players, and no one has ever done it more than twice. You're talking about five extra-base hits for every eight games played during the season at a minimum. There's a reason it has only happened 15 times in history and only six times since 1950. Here's the 100 extra-base hit club:

* ISO is isolated power, which is simply slugging percentage minus batting average. It removes singles to give you extra-bases per at-bat. The 2013 MLB average was .143 ISO, for reference.

Some observations and minutiae:

• 1932 Chuck Klein holds the distinction of posting the lowest slugging percentage in a 100 extra-base hit season at a mere .646. Slacker. Belle had the fewest total bases at 377.

• Not only did two players (Klein and Foxx) record 100 extra-base hits in 1932, they did it in the same city. The Athletics didn't move from Philadelphia to Kansas City until 1955.

• Three players cracked 100 extra-base hits in 2001 and all three have been connected to performance-enhancers: Bonds and Sosa have been linked to banned substances while Helton played in the friendly confines of Coors Field. Thin mountain air enhances performance, no? Helton is the only player in history with back-to-back seasons of 100 extra-base hits.

• Gonzalez probably qualifies as the most random 100 extra-hit man. Aside from that big 2001 season, he never recorded more than 80 extra-base hits in a season and only four times did he top 70+. Every other one of those players is either in the Hall of Fame, has an excellent Hall of Fame case, or remained on the ballot for multiple years. Gonzalez fell off the ballot this year after receiving only five votes (0.9 percent).

• Ruth and Gehrig are just so fascinating. They're the only players in history with 110+ extra-base hits in a season and they're two of the 10 greatest players ever. Maybe two of the of the top five. Yet they were on the same team at the same time for nearly their entire careers. Crazy.
